Answer: 7) No 8) No
Step-by-step explanation:
According to the Pythagoras theorem of the right triangle,
Square of largest side = Sum of square of other two sides.
8) Given sides: 5cm, 12cm, 14cm
Here, Largest sides = 14 cm
[tex]5^2+12^2=25+144=169\neq14^2 \ \ \ [14^2=196][/tex]
These sides do not represent a right triangle.
7) Given sides: 9m, 4m, 5m
Largest side = 9 m
[tex]4^2+5^2=16+25=49\neq 9^2 \ \ \ \ \ [9^2=81][/tex]
These sides do not represent a right triangle.
Which equation can be used to find 150% of 500?
Pls ignore that I selected C.
Answer:
A?
Step-by-step explanation:
A is the only one that makes sense, becaues 150% of 500 is 750.
150/100 = 150%
5/5, I believe, just represents the 5 in 500.

2 1/2 = 5/2
3/5 / 5/2 = 3/5 * 2/5 = 6/25
Lin runs 2 3/4 miles in 2/5 of an hour. Tlyer runs 8 2/3 miles in 4/3 of an hour. How long does it take for each of them to run 10 miles
Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h

2 w = 2p - 3z
a Find w when p = 8 and z = -2
Answer:
11
Step-by-step explanation:
2w = 2×8 - (-2×3)
2w = 16 - (-6)
2w = 22
w = 11
given f (x) = 3x+4, find f (2)
f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.
So in this problem, we're putting a 2 into our function which
means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.
So f(2) = 7 or the value of the function at 2 equals 7.
[tex]f(x) = 3x + 4[/tex]
Find f(2) by substituting x = 2 in the equation.[tex]f(2) = 3(2) + 4 \\ f(2) = 6 + 4 \\ f(2) = 10[/tex]
Therefore the value of f(2) is 10.
Meaning of f(a) and substitution in functionf(a) means the value of f(x) is ... at x = a. Same goes to the f(2) = 10. It means the value of f(x) = 10 at x = 2.
Answer[tex]f(2) = 10[/tex]
find the slope of the line
Answer:
Undefined
Step-by-step explanation:
The graph shows a vertical line. All vertical lines have a undefined slope.
This is because that while using the slope formula you will end of with the denominator being 0. You cannot divide by zero.

You are Gina versus the 40% of the students to apply. All the students in the University at six, 35% actually enroll. It's 10,000 students apply, how many actually enroll?
Answer:
1,400 students
Step-by-step explanation:
Calculation for how many actually enroll
First step is to calculate the numbers of students that was accepted
Numbers of students accepted=10,000 students*40%
Numbers of students accepted=4,000 students
Now let calculate the numbers of students that was enrolled
Students enrolled=4,000 students*35%
Students enrolled=1,400 students
Therefore the numbers of students that actually enrolled is 1,400 students
A mechanic makes $350 /week. If 20% of his income is deducted for taxes, how muchd id the mechanic bring home as pay?
Answer:
$280
Step-by-step explanation:
Step one
Given data
A mechanic makes $350 /week
20% of his income is deducted for taxes
Required
the mechanic's take-home pay for the week
Step two:
let us find 20% of $350
=20/100*350
= 0.2*350
=$70
Therefore the take-home pay is
= 350-70
= $280
In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Answer:
500 students
Step-by-step explanation:
In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Let the number of students enrolled at the high school be represented as x
Hence:
25% of x = 125
25/100 × x = 125
25x /100 = 125
Cross Multiply
25x = 125 × 100
x = 125× 100/25
x = 500 students

Evaluate h(x) = -2x + 9 when x = -2.0. and 5
Answer:
h(-2) = 13
h(5) = -1
Step-by-step explanation:
Given the function
h(x) = -2x + 9
Evaluating at x = -22
substitute x = -2
h(-2) = -2(-2) + 9
h(-2) = 4 + 9
h(-2) = 13
Therefore,
h(-2) = 13Evaluating at x = 5
Given the function
h(x) = -2x + 9
substitute x = 5
h(5) = -2(5) + 9
h(5) = -10 + 9
h(5) = -1
Therefore,
h(5) = -1.
A shop owner offered a 20% discount off the regular price of a mirror. The amount of the discount is $3
Answer: $15
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.

Which of the following expressions is equivalent to 2x + y − 4y + 8?
Question 10 options:
A. 2x + 3y + 8
B. 3x − 4y + 8
C. 2x − 4y + 8
D. 2x − 3y + 8
Answer:
2x - 3y + 8
Step-by-step explanation:
If you combine like terms
(In this case "y" and "-4y")
You get "-3y"
The rest of the equation stays the same, as there are no more like terms.
Therefore the answer is the D.

Answer:
3 3/4
Step-by-step explanation:
3/4 * 1/5
First you would turn 1/5 into a reciprocal
Now your equation would be 3/4 *5/1
Now you multiply 3/4 * 5/1
15/4
Now find 15/4 as a mixed number
15/4 as a mixed number would be 3 3/4
Therefore there are 3 3/4 1/2 cup servings in a 3/4 cup of ice

Answer:
Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0
Step-by-step explanation:
We need to solve the expression: [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]
Solving the expression:
We will use simple maths rules to solve the expression
[tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex]
Subtracting 1/2 on both sides and simplify
[tex]x+\frac{1}{2}-x-\frac{1}{2}=\frac{1}{2}-\frac{1}{2}\\x-x=0\\0=0[/tex]
Solving the given expression [tex]x+\frac{1}{2}-x=\frac{1}{2}[/tex] we get 0=0
So, the expression is true for all values of x. there will be infinite solutions to the system.
What is the solution to this system of equations? 2t + w = 10 4t = 20 − 2w A. It has no solution. B. It has infinite solutions. C. It has a single solution: t = 4, w = 2. D. It has a single solution: t = 2, w = 6. E. It has a single solution: t = 6, w = -2.
Answer:
B. It has infinite solutionsStep-by-step explanation:
Given the system of equations:
2t + w = 10 ..... 1
4t = 20 − 2w ... 2
From 1:
w = 10-2t ...3
Substitute 3 into 2 to have;
4t = 20 - 2(10-2t)
4t = 20-20+4t
4t = 4t
Let t = k
Substitute t = k into 1 and get w;
From 1: 2t + w = 10
2k + w =10
w = 10 - 2k
k can take any integers. This shows that the solution to the equation is infinite
